Setup for Backup Server:
- Configure forwarding of root’s email to GroupWise System Admin resource:
echo user@test.com > /root/.forward
- Create/modify /etc/rsyncd.conf. See example Backup Server rsyncd.conf.
- Enable rsync daemon: chkconfig rsyncd on
- Start rsyncd: rcrsyncd start
- Change into the backup volume/directory:
- For a NSS BACKUP volume: cd /media/nss/BACKUP
- For a XFS /backup directory: cd /backup
- Create the backup folders for the primary server:
mkdir primaryservername
mkdir primaryservername/APPS
mkdir primaryservername/backup
mkdir primaryservername/boot
mkdir primaryservername/etc
mkdir primaryservername/GW
mkdir primaryservername/mbr
mkdir primaryservername/SHARED
mkdir primaryservername/USERS
- Create the backup folders for the backup server:
mkdir backupservername
mkdir backupservername/backup
mkdir backupservername/boot
mkdir backupservername/etc
mkdir backupservername/mbr
- Modify /etc/exports to export the BACKUP volume and /install directory:
- /install *(ro,sync,root_squash) 10.1.1.0/255.255.255.0(rw,no_root_squash,sync) 10.1.2.0/255.255.255.0(rw,no_root_squash,sync)
- For NSS BACKUP Volume:
/media/nss/BACKUP primaryservername(rw,no_root_squash,sync,fsid=20) backup1(rw,no_root_squash,sync,fsid=20)
- For XFS /backup directory:
/backup primaryservername(rw,no_root_squash,sync) backup1(rw,no_root_squash,sync)
- Enable nfsserver: chkconfig nfsserver on
- Start nfsserver: rcnfsserver start
- Create backup script bkp_backupservername.sh. See example Backup Server Backup Script.
- Set executable permission: chmod +x bkp_backupservername.sh
- Create lst file. See example exclude.lst.
- Use crontab -e to edit the cron jobs and add the backup script:
- For a NSS BACKUP volume: @daily /media/nss/BACKUP/bkp_backupservername.sh
- For a XFS /backup directory: @daily /backup/bkp_backupservername.sh
Backup Setup for Primary Server:
- Configure forwarding of root’s email to GroupWise System Admin resource:
echo user@test.com > /root/.forward
- Create the backup folder: mkdir /backup
- Change into backup folder: cd /backup
- Create the mount folder: mkdir primaryservername
- Modify /etc/fstab to auto-mount the backup volume:
- NSS BACKUP volume:
backupservername:/media/nss/BACKUP/primaryservername /backup/primaryservername nfs rw,intr,proto=tcp,rsize=32768,wsize=32768 0 0
- XFS /backup directory:
backupservername:/backup/primaryservername /backup/primaryservername nfs rw,intr,proto=tcp,rsize=32768,wsize=32768 0 0
- Mount the backup volume: mount -a
- Create backup script bkp_primaryservername.sh. See example Primary Server Backup Script.
- Set executable permission: chmod +x bkp_primaryservername.sh
- Create lst file. See example exclude.lst.
- Use crontab -e to edit the cron jobs and add:
@daily /backup/bkp_primaryservername.sh
